Anyone have any issues with using Lipo's in a supervee? I know the ESC doesnt have any cut-off, but I'm talking about weight bias. Does the use of NiMh help keep the boat planted at higher speeds? The guys who are runing close to 40mph, are these speeds on 2-6cell packs, 2-7 cell packs, or is it possible on 2-7.4 lipo packs? I was going to try 2 orion 4800 packs, but any input would be appreciated.
